'Purchasing' in the Bible

Joseph collected all the money to be found in the land of Egypt and the land of Canaan in exchange for the grain they were purchasing, and he brought the money to Pharaoh’s palace.

I gave myself to the work on this wall, without even purchasing a field. All my associates were gathered there for the work.

And [after] purchasing a linen cloth [and] taking him down, he wrapped [him] in the linen cloth and placed him in a tomb that had been cut from the rock. And he rolled a stone over the entrance of the tomb.
